Went very smoothly.
As in previous installs, it was necessary to restore some manual configurations, viz:
- modifications to salocal.cf.in
- add --noZip into zmbackup commands in crontab
- postfix-level whitelist as described in http://www.zimbra.com/forums/adminis...sing-rbls.html.
Note that zmbackup commands in crontab that contain options which aren't compatible with zmschedulebackup are simply deleted on upgrade. So I find it easiest to do zmschedulebackup -D to insert the default backup schedule, then I modify it. There are some bugzilla entries (41332, 45634, 50584, 54702, 54709) related to this issue, which will be fixed in Helix.
